Description

Main lock bolt and upper and lower connecting rod separable self-ejection structure Technical Field The invention relates to the technical field of locks, in particular to a self-ejection structure with a main lock bolt and an upper connecting rod and a lower connecting rod capable of being separated. Background In the existing lockset, the upper connecting rod, the lower connecting rod and the fluted disc assembly mechanism generally adopt a serial linkage structural design, namely, in the locking process, the upper connecting rod, the lower connecting rod and the fluted disc assembly mechanism always keep a linkage state and cannot realize the separation of the upper connecting rod, the lower connecting rod and the fluted disc assembly mechanism, so that the self-ejection function of the upper connecting rod and the lower connecting rod and the function of the fluted disc assembly driving lock bolt for back locking are mutually bound and cannot independently operate. The above-mentioned series linkage structure brings the direct defect that when the upper and lower connecting rods meet resistance or obstacle (such as foreign matter jamming, jamming caused by installation deviation, etc.) in the self-ejecting process, the movement of the upper and lower connecting rods is limited, so that the fluted disc assembly mechanism can not continue to move, finally the lock bolt can not normally extend, the back locking operation of the lock body can not be completed, and the use safety and reliability of the lock are seriously affected. Disclosure of Invention The invention provides a self-ejection structure with a main lock plunger and an upper connecting rod and a lower connecting rod capable of being separated, which solves the problems that when the upper connecting rod and the lower connecting rod encounter resistance or obstacle in the self-ejection process, the movement of the upper connecting rod and the lower connecting rod is limited, further the fluted disc assembly mechanism cannot continue to move, and finally the lock plunger cannot normally extend out, and the back locking operation of a lock body cannot be completed. The invention provides a self-ejection structure with a main lock bolt and an upper connecting rod and a lower connecting rod which are separated, comprising: The driving fluted disc set is arranged in the lock shell and is provided with an unlocking action and a back locking action; The connecting rod assembly is arranged in the lock shell and meshed with one fluted disc in the driving fluted disc group, and when the driving fluted disc group performs unlocking action or back locking action, the connecting rod assembly is driven to retract or pop up the lock shell; The back locking assembly is arranged in the lock shell and comprises a back locking tooth piece and a first elastic piece, the back locking tooth piece is meshed with one fluted disc in the driving fluted disc group, and the first elastic piece is connected with the back locking tooth piece; When the driving fluted disc group performs back locking action, the first elastic piece is used for providing elastic driving force for the back locking fluted disc so that the back locking fluted disc drives the driving fluted disc group to rotate in a back locking mode. The beneficial effects are that: through setting up the back-locking subassembly, when the drive fluted disc group runs into resistance or obstacle unable continuous motion, back-locking tooth piece and first elastic component can provide extra driving force for the drive fluted disc group, ensure that the drive fluted disc group accomplishes the back-locking action to the safety in utilization and the reliability of tool to lock have been improved. In an alternative embodiment, the driving gear disc set includes a first gear disc and a second gear disc, the first gear disc is meshed with the connecting rod assembly, the second gear disc is meshed with the counter-locking gear disc, the first gear disc has a pulling disc, the second gear disc has a push rod structure abutted to the pulling disc, when the counter-locking action is performed, the first gear disc rotates towards a first direction, the pulling disc and the push rod structure are abutted to drive the second gear disc to rotate towards the first direction, meanwhile, the counter-locking gear disc drives the second gear disc to rotate towards the first direction, when the unlocking action is performed, the second gear disc rotates towards a second direction opposite to the first direction, and the push rod structure and the pulling disc are abutted to drive the first gear disc to rotate towards the second direction. The beneficial effects are that: Through the cooperative work of the first fluted disc and the second fluted disc and the cooperation of the plectrum and the push rod structure, smooth operation of the driving fluted disc set in the back locking and unlocking actions is realized.
